Recent developments in biofuel demand and the rapid adoption of modern transgenic hybrids are changing production systems towards more corn after corn, more intensive tillage, higher plant populations, and ever higher crop residue levels at harvest. Meeting society’s needs for food, feed, and fuel from grain corn, and in the future from corn stover, requires continued refinement of tillage syst...

conservation tillage, a fast growing practice in iran, is considered as a means to achieve sustainability in agricultural systems. this study was carried out to determine the effect of tillage systems (no-tillage, minimum tillage and conventional tillage ) on yield and yield components of three irrigated wheat varieties. the field experiment was conducted at the experimental station of the univ...

Should I switch from conventional till to no-till wheat production? This is one of the most common questions asked by Oklahoma farmers, but it is also one of the most difficult to answer. There are several considerations when making this decision, and there is certainly no one-size-fits-all program for converting from conventional till to no-till wheat production. A few factors to be considered...

We established experiments on farmers’ fields at four locations in southcentral Alaska and two locations in interior Alaska. The southcentral Alaska sites were near Anchor Point (59 ̊45'N, 151 ̊39'W) on Edna Anderson’s farm, near Sterling (60 ̊32'N, 150 ̊39'W) on Paul Rumley’s farm, at Point Mackenzie (61 ̊24'N, 150 ̊04'W) on the Trytten Farm, and at Palmer (61 ̊39'N, 150 ̊04'W) on Peter Scorup’s farm ...

or no-till. Those who oppose this notion argue that no-till is equated with an abusively high use of herbicides and even genetically modified organisms (GMOs) are synonymous with unsustainable agriculture, with no-till taking all the blame. Unfortunately, both sides are right, and therefore, to get closer to the answer of the initial question, we have to take a deeper look into no-tillage syste...

to be the biggest problem associated with stand establishment. Previous work has indicated that drought Planting rhizoma peanut (Arachis glabrata Benth.) directly into stress, particularly in the 3 mo postplanting is one of grass sod may be practical for producers [e.g., cow-calf (Bos taurus) the main reasons stands fail to establish or establish production, low maintenance roadside or turf sit...

Biannual surface application of potassium (K) fertilizer prior to corn (Zea mays L.) in a corn–soybean (Glycine max (L.) Merr.) rotation has been common in conventional-till crop production in North America; however, whether this traditional K management practice is effective for soybean when both corn and soybean are grown with conservation tillage is largely unknown. This study evaluated the ...
